Police said the men robbed the Royal Farms store in the 400 block of Sixth Street shortly after 2 a.m.

Police said one of the men scouted the store to make sure it was clear before the two other men -- one armed with a weapon -- jumped over the counter and stole cash and cigarettes. The men fled on foot.

Detectives said a vehicle may be involved, possibly a dark-colored van, possibly a Dodge or a Plymouth.

Police described the first man as black, 5 feet 7 inches tall, 165 pounds, in his 20s and with a cornrow hair style. He was last seen wearing a black tank top, dark cargo shorts, wire-rimmed glasses and a multicolored wristband on his right wrist. He appeared to be the lookout, police said.

Police said a second man, armed with a semiautomatic weapon, as black and 5 feet 10 inches tall. He was last seen wearing a gray hooded sweatshirt, blue jeans, brown belt and possibly New Balance tennis shoes.

The third man, police said, was carrying a purple backpack. He was described as a black man in his 20s who is 5 feet 8 inches tall with a medium build. He was last seen wearing a black long-sleeved hoodie, gray undershirt and black jeans with stripes on the side of his shoes.
